Mike Tyson is turning his rough-and-tumble life into a one-man show. The boxer will debut his “Mike Tyson: Undisputed Truth” with a one-week Las Vegas engagement in April. Playwright Randy Johnson told the L.A. Times it will sort of be like the one-person plays staged by Carrie Fisher and William Shatner. But no pugilist moves, he promised: “Mimicking boxing would be very cheesy. We’re keeping this authentic.”
